Indoloquinones, Part 5: Palladium-catalyzed total synthesis of the potent lipid peroxidation inhibitor carbazoquinocin C

The efficient palladium-catalyzed oxidative coupling of an anilinoquinone and subsequent regioselective introduction of the heptyl side chain provide the antioxidative substance carbazoquinocin C in four steps and 36% overall yield from aniline.

Indoloquinones, part 7. Total synthesis of the potent lipid peroxidation inhibitor carbazoquinocin C by an intramolecular palladium-catalyzed oxidative coupling of an anilino-1,4-benzoquinone

A highly efficient total synthesis of the potent lipid peroxidation inhibitor carbazoquinocin C is presented. The key-step is a palladium(II)-catalyzed oxidative cyclization of an anilino-1,4-benzoquinone to a carbazole-1,4-quinone which proceeds in up to 91% yield. Using this approach the natural product is obtained in four steps and 39% overall yield starting from aniline.
